Hello, I configure dbcache 90m for my data and heap size is 150m, but when I run multi-thread update on my store, the exception happened, and I can't restart the SN.
by the way, I have followed the introduction for compute dbcache and heap size.

which implies that something else might be wrong with the JVM running on that machine. While 90M is a pretty small cache for a NoSQL node, the node should still come up, unless (a) the node has been operating with a much larger cache in the past, and the node was not shut down cleanly before or (b) The JVM heap is not really able to access all its memory.

Hello,
I assign 90M which is computed by "java -jar je.jar DbCacheSize -records 1000000 -key 10 -data 20", and 90M is more than the max Bytes for Cache Size.

bty, I want to know what is the difference between "Database Cache Size" and "internal Node Usage by Btree Level" ? How do I set the value for both?

Could you please send any policy parameters that you are setting in your configuration step?

The Internal Node Usage by Btree Level is an estimate of how much space the Internal Nodes of the B-tree will take in the cache. It is not a parameter -- only an estimate given by DbCacheSize. The Database Cache Size can be set with
